COLUMBUS, Ohio — Roy Devin Marble scored 22 points, Aaron White added 19 and No. 20 Iowa ended the game on a 22-9 run to hand No. 3 Ohio State its second loss of the week, 84-74 on Sunday.

Melsahn Besabe had 11 points and 10 rebounds, Mike Gesell added 11 points and Jarrod Uthoff had 10 for the Hawkeyes (14-3, 3-1 Big Ten), who ended a string of eight straight losses to the Buckeyes.

LaQuinton Ross scored 22 points, Amir Williams had 11 and Lenzelle Smith Jr. 10 for Ohio State (15-2, 2-2), which had opened with 15 consecutive wins. The Buckeyes fell 72-68 in overtime at No. 5 Michigan State on Tuesday night.

It was Iowa’s first win over a top 5 team since an 83-65 victory at No. 2 Missouri on Dec. 15, 2001.

Iowa was 0-2 on opponents’ home courts coming in. Their three losses have come against teams with a combined 45-2 record (Villanova, Iowa State and Wisconsin) — with each loss coming by five or fewer points.

The Hawkeyes had not won in Columbus since 2004, losing on their last seven trips.

No. 12 LOUISVILLE 71, SMU 63

LOUISVILLE, Ky. — Luke Hancock had a career-high 23 points, including two free throws with 46 seconds remaining, for Louisville in a meeting of Hall of Fame coaches.

Hancock’s second straight 20-point game helped Rick Pitino’s Cardinals (14-3, 3-1 American Athletic Conference) get the final word in his first collegiate matchup against Larry Brown and his Mustangs (11-4, 1-2).

Making his first start despite dealing with a left Achilles issue, the senior guard made 8 of 15 from the field — 4 of 9 from 3-point range — to help keep Louisville ahead in a tense game that Montrezl Harrell finally settled with a dunk and a block after Hancock’s free throws.

Markus Kennedy had 12 points and eight rebounds in his first start of the season for SMU while Shawn Williams added 10 points. The Mustangs hit just 24 of 65 from the field (a season-low 37 percent), well below their league-best 50 percent mark coming in.

SMU made just 13 of 25 free throws and were only 2 of 11 from beyond the arc.

No. 13 SAN DIEGO ST. 79, AIR FORCE 72

AIR FORCE ACADEMY, Colo. — JJ O’Brien had 18 points and 11 rebounds as San Diego State extended its winning streak to 13 games.

It is the second-longest winning streak in school history for the Aztecs (14-1, 3-0 Mountain West) and it continues their second-best start ever behind 20-0 in 2010-11.

Tre’ Coggins had 29 points, including five 3-pointers, for the Falcons (8-7, 2-2), who led for much of the first half before trailing 31-27 at the break.

The Aztecs held a 39-30 rebounding edge including 17-6 on the offensive end. The Aztecs were 7 of 14 from beyond the arc while the Falcons were 7 of 20.

Colorado (14-3, 3-1) never recovered after leading scorer Spencer Dinwiddie crumbled to the court late in the first half after his left knee buckled while dribbling on a fast break. Dinwiddie had to be helped to the locker room by teammates and did not return.

The Huskies outscored the Buffaloes 49-29 after Dinwiddie’s injury.

Josh Scott led Colorado with 15 points. Askia Booker, the reigning Pac-12 player of the week, was 0 for 9 from the field and went scoreless for just the second time in his college career.
